LETTER-ING l Application filed srcn To all whom 'it may concern 4Be it known that I, JAMES A.. lvicllonnan, a subject of Great Britain, and a resident of the city of New York, borough et Brooklyn, county of Kings, and State of New lork, have invented certain new and useful lm provements in Lettering-Machines, oi 1#-.hich the following is a full, clear, and specification, such as will enable carers skilled in the art to which it appertains to make and use the same.

This invention relates to typewriting machines, and more particularly to that class of such machines which permit of Writing on a dat surface without the employment ci' cy'- lindrical platens which ordinarily hold the material to be Written upon Within the body of the machine.

One of the objects of my invention is to provide a machine 'for typcwriting lettering or descriptive matter on large maps, working drawings and the like, which, owing to the size of such drawings or maps, as Well as other diliiculties, cannot be lettered by the ordinary typeivriting machine, and, as such work is 110W done by hand, by skilled drafts menemployed Jfor that purpose, -which is a slow and laborious operation, consuming much time, and involving considerable money expenditure, it will be evident that, by providing a machine which will print such Work to be done accurately and expedi tiously by employees more or less unskilled" .in drafting Work, great economy will result. v

Another object of my invention is to provide a. machine which, when placed on the map or drawing to be lettered, may be quickly shifted 'from one position lto another, as, for example, from a position in Whichthe machine writes on a line parallel to one edge of the map or drawing, to a position at an inclination thereto.

The foregoing, as ivell as other objects, Will be readily apparent from the *following description, taken in connection 'ith the accompanying drawings, in which,W

Figurel is a plan vievv of the device; Fig. 2 is a side elevation; Fig. 3 is a detail elevation; and Fig. 4 is a' detail plan. y

It will be understood `that so .ffar as concerns the type bar operating mechanism, the drawings are in part more or less diagram- .matic, since various forms and arrangements of type bars and operating mechanism therefor may be employed, and in this application Specicatien of Letters Patent.

no invention is claimed for any particular form or arrangement thereof.

Referring to the construction illustrated, and B represent two parallel longitudinally eitending rails. which at their ends are conn cbed by tivo transverse rails C, D, united thereto in any desired manner, so as to 'form a thoroughly rigid frame or base.

The longitudinal rails A, B, are provided with angularly shaped uprig ts A1, which carry one or more balls A2, to act i bearings ior the carriage E, mounted on the plate F, the latter having fingers F1 projecting with in theuprights A1. The support A1 also carries a longitudinally extending rack bar N Wrack bar ll; said pinion being actuated in any suitable manner. The type Abars -are illustrated in Whole at lll, the type being at the upper portion thereto as at K2. and the bars being pivoted at, say, K3: the direction of movement thereof being indicated in dotted lines. The keys for operating said bars are indicated at L, the spacing keys and upper and lower case keys at M, N and O, respectively; all ot this mechanism being carried by a suitable frame indicated at P. The trame li also carries a guide Q for a ribbon Q1, the type bars making their impression through the open portion of the guide indicated at Q2. It u'ill be understood, however, that any form of'ribbon guide. operating by anv well known form ot ribbon operating mechanism mayV be employed, the form of ribbon guide shown being designed more particularly here for diagrammatic illustration.

lll/ach of the end. rails C. D, is provided with openings R, R1. within each of which RG formed on the end lfaileGlfllj Jxtaposed to `-nach of the rollers RR," '1s a friction member indicated at S, S1; each of these friction members comprises a head rtion T 'provided with outwardly exten ing pins or projections, T, havin Pivotally .connected to.",eaoh,..setV of. frio' tionmembers, S, Shisanopenting member U, having a pluralityof levens. .Ufthe lirst mentioned lever beiiigronnected by a link V to the head T ofjh friioll member S, and the latter lever bing connected by the link Vto the headT of the friction member S, insuch mannerthat by ressing the saidlevers toward leach otherf, A'echoes Tz are withdrawn ,fromzthefrollers R2, R3,

' against the action ofthe spr s T.. elily apparent The operation will be r from the foregoing description.; The l de vice is placed upon any portion of the' article to be written upon,- indicated `at X, which, for example, ,we will here assume to be a map of large size, say `siiil feet-squarethesame bein carried/onV the:=rollers. R?, R; the handles U1, are then: Qpratedto re lease the shoes T2 fromthe saidroller's, and the device may then be moved ,to ,anyportion of the map at whichtheJwork of .lettering is-tobegin. The type bars arenianipu lated to do any portion; of the work Irunning along parallel lines, parallel, for example, to the upper edge of the,map, the carriage `E traveling on the longitudinal` rails A, B,

,and the type bar mechanism, being ,capable l of movement along the transverse rails H, I.

lvhemhowever, it` is desired. to letter or place words of 4description-z,alon,e;,lines at different angles to the parallel lines just referred to' the handles U, U1, are again pressed to release the shoes T?, 'andthe machine may be quickly shifted to such new position; or from one position en the map, by the same means, the device may be readily and quickly moved from one endof the. map to the other, or from the `top ,to the bottom or to any intermediate position, without vdanger of crumpling or marring the surface in any manner.

on'ne myself tothe precise details ot conv struction and arrangement of the invention herein set forth, as modifications may be dmade,without departing from the spirit of the invention, as defined by the appended What I claim is: L combination with ty/pewriting mechanism for typeA bars adapted to write on a flat surface of a base including a plurality of parallel rails, revoluble means sup porting said base and on which the same may -be bodily moved to'any position u on, without removing it from, said fiat suriiace, and means adapted to lock said revoluble means against movement, to retain said base inra .fixed position.,

`2. The combination with typewriting mechanism of a base on which sald mechanism is adapted to move longitudinally, said base includinga plurality of parallel rails, rollers supporting the ends of said ybase upon which said base may be bodily moved from andto any desired operating position, means` adapted ,to hold said rollers, and thereby ,hold saidbase, in a fixed position, and means whereby said holding means may be released to permit movement of said rollers.

43, The combination with typewriting mechanism including type bars adapted to write upon a fiat surface, of a base tor said. mechanism, means whereby said mechanism may be moved longitudinally and trans versely of said base, rolling means supporting said base whereby the latter may be bodily movedto any position upon, without removing it from, said fiat surface, and means adapted to lock said rolling means against movement, to retain said base in a fixed ,position 4. The combination with typewriting mechanism including' type bars ada ted to write upon a flat surface, of a base or said mechanism, means whereby said mechanism may ,be moved longitudinally and transversely of said base, rollers .supporting said base,4 whereby the latter vmay be bodily moved to any position u on. without mov ing ;it from, said flat sur acc, holding mem bers adapted to Contact with and normally hold said rollers in :L fixed position, and manually operated means `for releasing said holding members from contact with said rollers.
